First I'm sure you meant to only use one dot between this and
And next, I'm glad you posted here because otherwise you
might go on thinking levels and depths are the same thing, BUT (and
it is a big but
) couldn't you have tested this yourself in probably
about 1/1000000th the time it takes to get an answer?
As I'm sure you must have figured out by now, the correct
answer is display_mc.circle1_mc.
Also I think your createEmptyMovieClip structure is a bit
wonky. I know you didn't ask, but hey you get what you pay for!
the createEmptyMovieClip() method does return a reference to
the newly created clip. But I think your usage (while not
technically wrong) has the potential to be confusing. Why are you
creating a variable called display_mc to hold a reference to a clip
called display_mc? They have the same name, but one is the thing
itself and the other a reference to it. Seem like a great place to
get confused in the future. Here is what I would do.
Your usage of the initObject in the creatEmptyMovieClip is
just fine, I was just showing you how you could use the returned
variable to change a property (like _alpha) as well as invoke a
method (like attachMovie()).
